Gmail is Google’s web-based email service, launched in 2004. Today it’s one of the world’s most-used inboxes—powered by large-scale spam filtering, phishing protection, and deep integration with Google Workspace tools like Drive, Calendar, and Meet.
This post focuses on the Gmail numbers people actually search for in 2026: estimated users, email-client share, spam blocked per day, key sender rules (SPF/DKIM/DMARC), and major product changes that affect everyday users and marketers.

Gmail User Count
Google does not publish a frequently updated public dashboard for Gmail users, but major coverage commonly cites about 1.8 billion Gmail users. Treat this as an estimate rather than a real-time metric.
Spam & Security: What Gmail Blocks Every Day
Google says Gmail’s defenses stop more than 99.9% of spam, phishing, and malware from reaching inboxes and block nearly 15 billion unwanted emails per day. These are some of the most reliable Gmail “scale” stats because they come directly from Google’s own statements.
Important Update for Marketers: Gmail Bulk Sender Rules
Starting February 1, 2024, senders who deliver 5,000+ messages per day to Gmail accounts must follow Google’s bulk sender requirements. These include authenticated email (SPF/DKIM) and additional standards designed to reduce spam and spoofing.
Gmail App Installs
The Gmail Android app crossed 10 billion installs on the Google Play Store—placing it among a small set of apps to hit that milestone.
2026 Product Change: Gmailify and POP Are Going Away
Google has announced it will discontinue Gmailify and remove the ability to “check mail from other accounts” using POP later in 2026. Users who relied on these features to pull third-party inboxes into Gmail will need alternatives such as IMAP-based account add-ons in the Gmail mobile apps, forwarding, or a separate mail client.
